Put the wormwood into the pot, add a lot of water, and cook it over the fire. Then take out the wormwood and throw it away, and pour the remaining water into the basin. When the water cools down, dip the mop in the water and drag it to one side to make the room full of wormwood flavor. In this way, it can also help to drive away mosquitoes in the room.
If there are more mosquitoes in the room, you can cut up a small amount of wormwood and put it into a jar, and then light them with fire. So they emit a lot of smoke.
